Updated at 527 AM CST Mon Nov 17 2025 - Low shower and storm chances this morning (Monday) and again tonight. - Well above normal temps today and Tuesday. - Unsettled pattern begins Tuesday night into Wednesday w/ increasing shower and thunderstorm chances. Widespread showers and storms Wednesday night through Thursday night. - A few strong to severe storms possible during the mid week time frame with primary hazard becoming heavy rainfall and associated flooding potential. && .SHORT TERM... (Through Monday) Issued at 1108 PM CST Sun Nov 16 2025 A stationary frontal boundary just south of the Red River will begin to lift northward early this (Monday) morning. Low clouds will increase in coverage early this morning as a low level jet continues to strengthen on top of isentropic lifting ahead of the warm front. As low level moisture and instability increase, consensus in latest hi-res model guidance suggest a few showers and thunderstorms developing near or just before daybreak across far east/northeast OK and northwest AR. This isolated to scattered showery activity will persist through the morning before dissipating and/or lifting out of the forecast area by midday. The warm front will slowly lift northeast through the daytime, reaching far northeast OK and west-central AR late in the afternoon. Low level clouds should break apart and thin in the vicinity and behind the boundary causing some well above normal temperatures in the upper 70s and lower 80s across much of eastern OK. Temperatures should stay in the low-mid 70s and even upper 60s ahead of the warm front. Although relative humidity/dewpoint temps shouldn`t be drastically low during the afternoon, limited and locally elevated fire weather conditions may take shape, especially west of Highway 75 in northeast OK where southerly winds will be breeziest and relative humidity values will be lowest (35-45 percent). Shower and thunderstorm chances will increase again late tonight (Monday night) into Tuesday morning , mainly for areas in far eastern OK and northwest AR (20-40% chance). This is due to a strengthening low level jet developing, coinciding with the passing of the southern edge of a shortwave trough that may impact parts of the forecast area. CAMs show very little in the way of storm development at this time, but there will be enough instability, shear, and lift in place for isolated strong to severe storms if storms are able to develop. Will continue to monitor trends through the daytime. A weak cold front will be approaching from the north at the tail-end of the short term period. Mejia && .LONG TERM... (Monday Night through Sunday) Issued at 1108 PM CST Sun Nov 16 2025 A weak cold front will slowly move into northeast OK and far northwest AR Tuesday morning/afternoon before stalling over the forecast area, somewhere near the I-40 corridor, by Tuesday evening. This will cause slightly cooler temperatures in its wake, though temperatures are still forecast to be well above seasonal average. Highs will generally reach the mid-upper 70s north of the boundary and low-mid 80s south of the boundary. This boundary will lift northward late Tuesday night into Wednesday morning and strong southerly low level flow will begin to advect a deep plume of moisture into the area. Although a few isolated showers and thunderstorms may develop along the boundary Wednesday morning, latest models and ensemble data show the onset for higher and more widespread rain chances may not occur until Wednesday afternoon/evening across the forecast area. This is when models indicate a lobe of vorticity embedded in the southwest flow aloft will tap into the moisture and cause scattered to numerous showers and scattered thunderstorms. Some severe potential may exist initially as this activity gets going, but exact details are still unclear at this time. The bigger threat will be moderate to heavy rainfall that will lead to flooding, especially by Wednesday night into Thursday. PWATs are still expected to surge above 1.50 inches by Thursday morning, values near the 99th percentile for this time of the year. These PWAT values, as well as the heavy rain and flooding threat, will continue into Thursday evening before a downward trend begins and the heavy rain threat tapers off by Friday morning, with lingering showers into the afternoon. Next cold front looks to move through during the daytime Friday as the upper level low finally departs north and east of the area. Temperatures will drop closer to seasonal averages by the upcoming weekend behind the front. Things stay dry through at least Saturday. Forecast uncertainty increases drastically beyond Saturday with several differences in model data. Mejia && .AVIATION... (12Z TAFS) Issued at 527 AM CST Mon Nov 17 2025 MVFR ceilings at the eastern Oklahoma sites will improve to VFR this afternoon. Initially VFR ceilings at the Arkansas sites will likely lower to MVFR later this morning and then improve to VFR again by this evening. South winds will gust to near 25 knots at times today at the northeast Oklahoma and far northwest Arkansas sites. LLWS will be mentioned at the Arkansas sites tonight. Rain chances are too low at any TAF site to include in the forecast at this time. && .PRELIMINARY POINT TEMPS/POPS...
